FEATURES DESCRIPTIONS

Output Over-Current Limit and Short Protection

The modules include internal output over-current limit (OCL) and short circuit protection (SCP) circuits the OCL set point is lower than that of the SCP The response of SCP circuit is much fast than that of the OCL circuit The slowly increase of the output current will let module enter OCL protection when the current exceeds the OCL set point while the fast increase of the output current will let module enter SCP when the current exceeds the SCP set point When the modules enter OCL protection the output voltage will decrease while the output current is kept constant the output voltage will soft start to set point when the overload condition is removed The module will enter hiccup mode when it triggers the SCP set point The module will try to restart after shutdown If the overload condition still exists the module will shut down again This restart trial will continue until the overload condition is removed

Output Over-Voltage Protection

The power module includes an internal output over-voltage protection(OVP) circuit which monitors the voltage on the output terminals If this voltage exceeds the OVP set point the module will shut down and then restart after a fixed delay time (hiccup mode) please refer to figure6 for detail

Over-Temperature Protection

The over-temperature protection consists of circuitry that provides protection from thermal damage If the temperature exceeds the preset temperature threshold the module will shut down and enter into latch mode and all components will not exceed their absolute maximum temperature ratingsThe module will not recover until the input source is powered on again

Remote OnOff

B62SR24125C has Enable control function This Enable PIN is designed on the primary side of converter the converter will turn on when the Enable PIN connected to VIN+ and turn off when the Enable PIN connected to VIN- or floating

DESIGN CONSIDERATIONS Parallel connection of multiple units

Two units parallel operation is verified please contact Delta if more than two units need to be paralleled While parallelling multiple units the impedance of the cables from unit to junction point of each unit should be

within plusmn5 of each other

Figure 13 suggested parallel connections

EMC The converter has the internal EMI filters and meet the EMC standards EN12895 30-1000MHz 34-45dBuVmThe test result is showed as below Conditions Vin=48V Io=125A 10m measure distance

THERMAL CONSIDERATION

The following figure shows the location to monitor the temperature of base plate Before customer decides to use

this DCDC converter a thermal evaluation need to be done to make sure the temperature of base plate is lower

than that read from below thermal curves (Figure23~27 base on different input voltage)
